Fermentors are used to increase culture yield and productivity of bioengineered cells. After screening multiple microbial or animal cell culture candidates in shake flasks, the next logical step is to increase the selected culture’s biomass with the fermentor. This video demonstrates the setup and operation of a typical benchtop bioreactor system.

Bioreactors are used to grow organisms in large volumes, thereby enabling the production of mass quantities of the target product. These reactors can be batch reactors, which contain all of the components needed for cell growth, or continuous reactors, which have inlet and outlet ports allowing for the addition of fresh growth media and the removal of cell waste. This video presents batch and continuous reactors and demonstrates the use of bioreactors to grow bacteria in the laboratory.

FAQs
A bioreactor’s components form an integrated culture environment rather than independent parts. The vessel contains the biological material, the agitator supports mixing, tubing enables fluid and gas transfer, and sensors connect culture conditions to monitoring and regulation. Temperature-control equipment adds another layer of control, helping maintain conditions that support consistent biological performance during an experiment.
Sterile operation depends on assembling fluid and gas pathways that limit opportunities for contamination. Tubing, gas inlets and outlets, and the culture vessel must work together without compromising controlled transfer. This matters because contamination can interfere with cell, microorganism, or tissue growth and reduce the reliability of results. Careful assembly therefore supports repeatable biological experiments.
Sensors provide information about conditions that must be monitored during culture, particularly pH and temperature. Their integration with the vessel and control systems allows those variables to be regulated rather than merely observed. This supports a defined laboratory environment and helps researchers evaluate biological performance under controlled conditions, which is essential when comparing experiments or assessing process behavior.
Mixing and aeration address different aspects of the culture environment. The agitator promotes mixing within the vessel, while the gas inlet and outlet support aeration and controlled gas movement. Monitoring and regulating both processes helps maintain the intended conditions for growing cells, microorganisms, or tissues. Their coordinated operation is therefore important for consistent culture behavior.
Assembly brings together the culture vessel, agitator, tubing, sensors, gas inlet and outlet, and temperature-control system. These components are connected so that culture conditions can be monitored, fluids and gases can move through the system, and the environment can be regulated. Integrating the parts into one support system provides the operational foundation needed before biological performance can be evaluated.
A completed system can support cell culture, microbial production, tissue engineering, and broader bioprocess studies. Its controlled environment allows researchers to examine biological performance while monitoring variables such as mixing, aeration, pH, and temperature. The same assembly principles also help provide a foundation for scaling experiments, making results more useful for comparing conditions or developing larger processes.
Consistent assembly helps ensure that fluid transfer, gas movement, mixing, sensing, and temperature control operate through a defined system each time. That consistency supports reproducible culture conditions and makes biological outcomes easier to evaluate. It also provides a foundation for scaling experiments, allowing researchers to investigate whether observed cell, microorganism, or tissue performance remains consistent under expanded process conditions.
